I would drop Durazao from your hitters bench and pick up Reggie Sanders, and from your Pitchers bench I would drop washburn and pick up either Penny or Eaton.
As for Alex Sanchez, I dont see him having much fantasy value this year. He is already BARELY holding onto the job at centerfield, with other players just ready to snag that spot. I read recently in an article that he had an ordinary pop fly in the outfield, and he dropped it. I would assume the Tigers Staff wasn't to pleased about that. So I would stay away from Sanchez.
To Cure your steals problem, maybe you could involve yourself in a trade.
